“Donald Trump is a delusional narcissist and an orange-faced windbag,” he said on Comedy Central’s “The Nightly Show.”
“If the dirt doesn’t go away, it will keep scratching your cornea until eventually it blinds you with all its filth. A speck of dirt is way more qualified to be president.”
Paul also likened Trump to Nazi propagandist Joseph Goebbels.
“I’m not sure I would say Trump is Hitler – Goebbels maybe,” he said.
Asked if he would kill an infant Hitler or Trump if he went back in time, Paul said he wasn't "seriously" comparing Trump to either Nazi.
"I have compared him to Gollum from ‘Lord of the Rings,’” he jokingly added, referring to a monster from the fantasy series.
Paul also took a shot at Dem contender Sen. Bernie Sanders (I-Vt.), saying young people who supported him would end up disappointed.
“If you want Santa Claus and something free, then [you are] going towards Bernie,” he said.
“I think there are a lot of people out there who are more realistic about what they want. If you understand that really nothing in life is free, but you want freedom and opportunity, then [you are] coming our way.”
Paul urged libertarian-leaning voters to back him regardless of their party affiliation.
“On the right there are people who believe in economic liberty,” he said. "On the left, there are people who believe in personal liberty.
“What we are trying to do is join liberty together and say across the board, government ought to stay out of your life."
